Overview

SpecificityThis antibody does not detect human inducible NOS or rat brain nNOS.
ab5589 has been successfully used in Western blot and immunohistochemistry (paraffin and frozen) procedures. By Western blot, this antibody detects an ~140 kDa protein representing eNOS from human endothelial cells. Immunohistochemical staining of eNOS in Human vascular endothelial cells with ab5589 results in prominent staining of the epithelial cells.

We have received mixed feedback from customers regarding rat specificity; this is why we are temporarily removing Rat from tested species list and no longer guarantee it. Our laboratory is currently testing new lots so please contact our scientific support team (technical@abcam.com) for more information.

Cellular localizationCell membrane. Membrane > caveola. Cytoplasm > cytoskeleton. Golgi apparatus. Specifically associates with actin cytoskeleton in the G2 phase of the cell cycle and which is favored by interaction with NOSIP and results in a reduced enzymatic activity.

Thanks for sending the email again. Not sure what is going on but the attachement still did not appear on the email. However it seems the customer is very interested in getting a replacement so I'm happy to send one.
